Scarlett Johansson: Redhead to Strawberry Blond

The head-turner made waves this summer by going from a deep, dark red hair color to a lighter strawberry blond in a matter of months. Before you worry about all those harsh hair dyes affecting ScarJo’s beautiful ‘do, consider reader gabgayheart’s theory: “Do you think she’s just using a demipermanent color and it’s just fading? It seems like once a month, she’s dying it dark only to “fade to light” again.” Here’s hoping, gabgayheart!

Model Amber Rose—and Kanye West’s main squeeze—pulled off the most daring hair change of the summer by dyeing her bleached buzz cut bright turquoise! But before you whip out a bottle of hair dye to, well, DIY the look, consider reader dagnyt’s advice: “I’ve had blue hair… and purple and green and a few other colors that don’t appear in nature. It’s fun, although I don’t recommend it if you’re job hunting.”
